Why Crochet a Bikini Top? 

Crochet bikini tops are a popular trend in swimwear for several reasons. Making your own crochet bikini top creates a one-of-a-kind bikini that is different from anything you would find in a store. 

These projects are highly customizable, so you can choose just the color and stitch pattern you like, and even create your own unique designs. You can also adjust the fit of the bikini to your body. 

Crochet bikini tops are very comfortable to wear. The crochet material is breathable and dries quickly, making it ideal for swimming and lounging.

Making your own bikini can be a cost-effective option compared to buying one from a store, especially if you already have the materials needed. 

How to Crochet a Bikini 

Crocheted bikini tops are typically made starting with the cups, which are shaped with increases and decreases to make the cup the size and shape you need.  

Once that’s done the cups are joined to each other and a band may be added at the bottom of the bikini top for extra support. Then you will crochet straps to go over the shoulders and around the back so the top stays on your body. 

Tips for Crocheting a Bikini Top 

Crocheting a bikini top can be a fun and creative project, but it requires attention to the details before, during, and after stitching to ensure your project is a success. Here are some tips to help you successfully crochet a bikini top. 

First, consider your yarn. Many bikini tops use cotton yarn because it is durable when wet. It can get heavy and stretch when wet, though, so make sure if you are planning to get your bikini top wet that it is worked at a tight gauge. 

You can also use yarns with synthetic materials that are made for use in swimwear, or yarn with elastic content to help your bikini stay where it needs to be. 

Getting the correct gauge and having accurate measurements of the parts of your body you want to cover are essential in getting the right fit. 

To make sure your project doesn’t stretch when you launder it, consider hand washing even if the yarn you used is machine washable. 

Adding Fabric Lining to a Crochet Bikini Top

Crochet swimsuits and bikini tops are fun to stitch, but they don’t always give the level of coverage and support you might like. 

Adding a fabric lining to a crochet bikini top can provide extra coverage, as well as helping to prevent the crochet stitches from stretching or becoming misshapen. It also can provide more comfort and confidence when wearing the bikini top.

Here’s how you can add fabric lining to your crochet bikini top: 

  1. Cut the lining out of the fabric according to the pattern or trace your crocheted cups, leaving a little extra fabric around the sides for a seam allowance. 
  2. Fold the seam allowance to the back side of the fabric and pin the lining to the inside of the crochet bikini top, making sure that the edges match up. 
  3. Sew the lining to the top using a sewing machine or by hand. Use a zigzag stitch or a stretch stitch to ensure the fabric can stretch with the crochet top. 
  4. Try on the bikini top to make sure that the linen is comfortable and fits properly. 

Supplies Needed to Crochet a Bikini Top

Yarn for Bikini Tops 

When choosing a yarn for a crochet bikini top, there are several qualities to look for to ensure that the finished garment is comfortable, supportive, and long-lasting. 

Look for a yarn that is suitable for summer wear and can withstand exposure to water and sunlight. This means choosing a yarn that is lightweight, breathable, and quick-drying. 

Cotton, linen, and bamboo yarns are all good options for crochet bikinis, as they are soft and comfortable against the skin. 

It is also important to choose a yarn that has good elasticity and stretch, this makes the bikini top stay in place and hold its shape over time. 

Synthetic yarns such as spandex or blends of natural and synthetic fiber can provide the necessary stretch and support to ensure a good fit. 

With all that in mind, here are some of the most used and loved yarns used in making bikini tops.

Notions and Tools Needed to Crochet a Bikini Top

In addition to your yarn, you’ll need a few other supplies to successfully crochet a bikini top: 

  • Crochet hook: It is recommended to use a hook that is one or two sizes smaller than the recommended hook size for the yarn to ensure that the fabric is tight and does not stretch too much.
  • A yarn needle should have a large eye and a blunt tip to prevent it from snagging or damaging the crochet stitches. This is key for weaving in ends and sewing pieces together if needed.
  • Stitch markers: Bikini top cups are often worked from the center out in rounds, and a stitch marker will help you see where the end of the round is. 
  • Scissors: A small pair of scissors is helpful for accuracy in cutting yarn. 
  • Tape measure: You’ll need to measure yourself and your project to ensure a good fit. 

Crochet Bikini After-Care Tips

A crochet bikini is a beautiful and unique summer garment that can provide years of enjoyment and use when cared for properly. To keep your crochet bikini looking its best and to ensure that it lasts for many seasons, it’s important to follow these after-care tips. 

  • Hand washing is best.  To maintain the shape and integrity of your crochet bikini, it's best to hand wash it in cool water with a mild detergent. Avoid using bleach or harsh detergents, as these can damage the crochet material. 
  • Rinse thoroughly. Make sure to rinse your bikini thoroughly to remove all traces of soap and detergent (as well as chlorine or salt). This will help prevent irritation the next time you wear the garment. 
  • Lay flat to dry. To dry your crochet bikini, lay it flat on a clean towel and shape it into its desired form. Avoid writing or twisting the bikini as it can cause stretching.  
  • Check for wear and tear. Regularly check your bikini for any signs of wear and tear, such as fraying or stretching. If you notice any issues, it may be time to repair or replace your bikini. 

Crocheting a bikini top is a fun project for stitchers of any skill level and is a great addition to your beach, pool, or festival wardrobe.
